Every September, businesses lose people and act surprised. Don’t be. The person who hands in their notice in September decided in August. September is just when they finally said it out loud.
Nobody quits over one bad Tuesday. They quit because a stretch of weeks told them something true about how much the business values them, and they believed it.
Why September gets the blame when August did the damage
September has a reputation. Job listings spike, LinkedIn fills up with “excited to announce”, and everyone nods like it’s just the season. It isn’t the season. It’s the lag. Most people don’t quit the day they decide to quit. They spend weeks working up to it: updating a CV quietly, taking a call at lunchtime, telling themselves it’s not that bad yet. By the time the notice lands on a desk in September, the decision was made weeks earlier, usually somewhere in a stretched, chaotic August where nobody checked in and the same person covered everything again.
The real reasons people start looking, and it's rarely about money
Ask a leader why someone left and you’ll usually hear “they got a better offer” or “it was always going to happen eventually.” Maybe. But the businesses that sit down and dig into exit conversations hear something else, again and again. I didn’t feel like anyone noticed. I was covering for three people and nobody said thank you. I raised it in July and nothing changed.
Salary’s rarely the real issue. What matters more is whether people feel seen, whether the business runs on fairness or on whoever’s too polite to say no, and whether raising a problem leads to something changing.
Three excuses leaders tell themselves, and the truth underneath them
MYTH: “They just wanted more money.”
REALITY: Money’s rarely the whole story. It’s usually the easiest reason to give when the real one, feeling overworked and overlooked, is harder to admit to.
MYTH: “It was always going to happen eventually.”
REALITY: Maybe. But “eventually” had a trigger, and it was probably a stretch of weeks where nobody checked whether the workload was sustainable.
MYTH: “That’s just how it is with this generation.”
REALITY: Every generation leaves jobs that stop feeling worth staying in. That’s not new. Pretending otherwise just means nothing gets fixed.
Building retention in before September, not after
Retention isn’t a September problem. By the time someone’s polishing their CV, you’re not retaining them, you’re negotiating with a decision that’s already been made.
The businesses that keep their best people aren’t the ones making counter-offers in September. They’re the ones who, in August, noticed who was quietly carrying too much, said thank you before someone had to ask for it, and fixed the thing that got raised in the summer instead of parking it until autumn.
If you’ve already sorted Cover Planning That Works and Fair Workload Distribution this August, you’re most of the way there. If you haven’t, September’s problem starts right there.
The takeaway
You can’t stop every resignation, and you shouldn’t try. But most of the ones that blindside leaders in September were entirely visible in August, if anyone had been looking. Look now. Ask the quiet ones how they’re doing. Say thank you before someone makes you say sorry instead.

Quick questions on employee retention
What’s a good employee retention strategy for a small business?
Start with the exit conversations you’re already having, informally, the ones where someone mentions they’re thinking about leaving before they’ve handed in notice. Take those seriously instead of waiting for the formal one. Beyond that: notice who’s overloaded, say thank you specifically rather than generically, and fix small problems before they become the reason someone leaves.
How do you know if someone’s about to resign?
There’s rarely one big sign, it’s more a pattern. They go quieter in meetings, stop pushing back on things they’d normally flag, their calendar looks lighter because they’ve stopped volunteering for extra work, or they start asking oddly specific questions about notice periods. None of these prove anything alone. Together, they’re worth a direct conversation.
